Yes, should be no problem. The config setup is the same and also the user file formats etc. are identical. I'am not sure for mysql databases, you might want to export them with mysqldump into a text file and then reimport them on the new server.

But what about user and groups accounts? What should I copy from old 32-bit system disk to the new one with installed 64-bit system? I understand I should install also all ISPConfig3 stuff, duplicate database, copy /var/www/ and? What should I do for example with virtual hosts files?
